METAL SCREEN Application filed January 14, 1881. Serial 110.508,?87.

This invention relates to window screens of the all metal type, theprimary object of the invention being to provide .a window screen whichwill be exceptionally strong and durable, pleasing in appearance, andformed replacement, in the field of the wire mesh or screen material maybe .accomplished with facility, and by persons unfamiliar withmechanics, the construction of the window screen, including a removablespline capable of being used indefinitely.

A further object of the invention is to provide a screen securing splineof a construction to readily adjust itself within the wire receivinggroove of the frame, in such a way as to set up a binding action toinsure against the wire mesh material becoming dislace p A still furtherobject of the invention is the provision of a metallic screen frameembodying angle bars to be used at the corners thereof, the angle barsacting to brace the frame at its corners.

Still another object of the invention is to provide a screen framewherein the wire mesh receiving portion of the frame is extended beyondthe frame, so that the wire mesh will be projected beyond certainhardware secured to the window frame. With the foregoing and otherobjects in view, which will appear as the description proceeds, theinvention resides in the combination and arrangement of parts and in thedetails of construction hereinafter described and claimed, it beingunderstood that changes'in the precise embodiment of the inventionherein disclosed, may be made within the scope of what is claimed,without departing from the spirit of the invention.

Referring to the drawings in detail, the window screen frame comprisesside members 5 and end members 6, the same being constructed of tubularsheet metal material, the outer upper surfaces thereof being formed withgrooves 7 the grooves being formed by bending the meeting ends of thesheet metal material together, as clearly shown by the drawings.

Due to this construction, a. shoulder 8 is provided, which shouldercooperates with the wire securing spline, in gripping the wire meshmaterial to the frame. The spline is indicated by the referencecharacter 9, and comprises a length of sheet metal material curved toconform to the curvature of the groove of the frame, in which it ispositioned,

the longitudinal edges of the spline being spaced appreciable distancesapart, so that they may move towards and away from each other. to permitthe spline to be positioned within the groove, and exert a lateralpressure on the wire mesh material at both sides of the groove, shouldthe edges of the wire mesh material extend throughout the entire widthof the, groove.

The splines comprise strips that are substantially straight and whichare used along the sides of the frame, the splines at the corners of theframe being rectangular in formation and mitered, as shown by Figure 15of the drawings, and indicated by the reference character 10.

The side and end bars of the frame are held together by means of thecorner sections 11 which are so constructed that they fit within theends of the side and end members, providing a binding fit therebetween.It will be seen that the frame may be readily disassembled andassembled, by persons unfamiliar with mechanics.

In order that the guide grooves of the frame may be extended to theupper and lower edges of the frame, the sides of the corner sections 11are left open, as at 10, permitting the side sections of the frame toextend to the extreme corners of the frame.

The outer surfaces of the side sections of the frame are formed withlongitudinal grooves 12 to receive the usual guide strip of a window,and over which the screen frame slides, the outer edges of the groovesbeing extended inwardly as at 13, to bite into the guide strip overwhich the frame moves, and also to retain the friction spring 22 andprevent displacement thereof.

Another form of the guide groove is indicated by Figure 6 of thedrawings, in which the inner edges are slightly curved inwardly as at14, Willie in Figure 7 of the drawings the inwardly extended portions 15are substantially sharp, to bite into the guide strip and retain thefriction spring.

Grooves 16 are formed in the side sections of another form of metallicframe, and are designed to receive guide strips of a particularconstruction.

As shown by Figure 9 of the drawings, the outer edges of the frame arecurved at 17 to facilitate the opening and closing of a pivoted screenframe, and prevent binding of the screen on the pivot side thereof, andas shown in this form of the invention, curved portions 18 are providednear the spline groove of the frame, to brace the frame in such a way asto insure against twisting or binding of the frame While in use.

In the form of the invention as shown by Figure 7, the portions of thesheet metal material are inclined towards the groove, as at 19,providing a reinforcement at this point, and lending a beveledappearance or effect to the molding.

Positioned in the guide groove at one side of the frame, is a metallicspring retaining member 20 which is formed with an opening near one endthereof, to register with an opening formed in the side section of theframe in which the spring retaining member is positioned, theregistering openings being provided to accommodate the tongue 21 formedat one end of the spring 22, which spring is curved upwardly to engagethe inwardly extended ribs 23 of the spring retaining member 20. Thefree end of the spring 22 is curved upwardly as at 24, so that I it willslide readily over the lower surface of the spring retaining member 20,and exert a pressure against the guide rib or strip, with which thewindow screen is used. This spring is used for retaining the screenframe in position when a screen frame is used, which is not providedwith inwardly extended portions 14 and 15 as shown by Figures 6 and 7respectively.

As clearly shown by Figure 13 of the draw ings, tongues 25 are formed atthe ends of the spring retaining member, and extend into 1 openingsformed in the bottom of the side'section of thescreen frame in which thespring is positioned.

Further modified forms of the frame are shown by Figures 11 and 12, inwhich I construction, portions of the metallic frame are pressedtogether and extended therefrom, pre senting a flange 26 at the insideof the frame, thefiange 27 which corresponds to the flange 26 and whichis shown in Figure 12 of the drawings, being constructed in a likemanner except that it is formed on the opposite or outside of the screenframe. These are astragal formations to be used on adjacent meetingstiles where two or more screens are used together in same opening.

Figure 10 illustrates a bar or cross ra1l constructed of sheet metalmaterial and formed in such a way as to provide a body portion 28 andlateral screen grooves 29 in which the screen splines 30 are positioned,to secure the screen or wire mesh material thereto.

In Figure 16, the frame is of a construction identical with that shownby Figure 1 of the drawings, with the exception that in this form of theinvention, an angle bar indicated by the reference character 40 isemployed at the corners of the screen frame, the ends of the angle barsbeing fitted between the straight surfaces 31 and curved surfaces oftheinner edges of the screen frame, bracing the corners of the screenframe against twisting.

In the modified form of the invention as shown by Figure 19, the bodyportion of the screen frame is indicated by the reference character 41,and as shown is formed with a right angled extension 42 extending anappreciable distance beyond the body portlon 41, where it is providedwith ascreen receiving groove 43, sothat the wire screen material may besupported in spaced relation with certain hardware, secured to a windowframe.

The frame shown by Figure 20, is substantially the same as that shown byFigure 19, except that the portion 44 thereof extends inwardly tocontact with the body portion 45, where it is extended at right anglesas at 46.

In Figure 21, the frame is shown as including a body portion indicatedat 47 and a right angled portion 48 that has a groove 49 to receive thewire mesh material. In this form of the invention the opposite side ofthe sheet metal material, indicated by'the reference character 50,extends towards the inner edge of the body portion, where it is formedwith a curved portion 51 fitted over the bead 52.

In Figure 22 a guide bar is illustrated. This guide bar indicated by thereference character 53, is constructed of a length of sheet metalmaterial, bent in such a way as to provide lateral extensions 54 whichare formed with openings to receive securing screws. A double guide barconstruction is indicated by Figure 23 of the drawings and includesspaced supporting'sections 55, that are designed to fit within the guidegrooves of the screen frames.

It might be also stated that the sections may be secured together attheir ends as by .welding, soldering, or in any other suitable manner toform a continuous rectangular screen.

From the foregoing it will be seen that due to this construction,straight surfaces 31 are provided in the spline grooves, which cooperatewith the irregular curved sides 32 of the splines positioned therein, tobite into the wire mesh material, and securely hold the same againstmovement.

It Wlll further be seen that the sections of the screen frame may bereadily disconnected and connected, or assembled by persons unfamiliarwith mechanics.
